Answer:
(C) j/j+80 and 36/k+36
Step-by-step explanation:
From the table attached :
Total Email (positive + negative) = j + 80
Number of positive Emails = j
Fraction of positive emails = (number of positive / total number of emails) = j / (j + 80)
Total phone calls (positive + negative) = 36 + k
Number of positive Emails = 36
Fraction of positive emails = (number of positive / total number of emails) = 36 / (k + 36)

See the attached figure.
m ∠KAJ = 170° & m ∠LAM = 80°
We should know that :
m ∠KAJ + m ∠LAM + m ∠KAL + m ∠MAJ = 360°
∴ m ∠KAL + m ∠MAJ = 360° - (m ∠KAJ + m ∠LAM)
∴ m ∠KAL + m ∠MAJ = 360° - (170°+80°) = 360° - 250° = 110°
But : m ∠KAL = m ∠MAJ ⇒⇒⇒ <u>Opposite angles.</u>
∴ m ∠MAJ + m ∠MAJ = 110°
∴ 2 * m ∠MAJ = 110°
∴ m ∠MAJ = 110° ÷ 2 = 55°
<u>So, the answer is : m ∠MAJ = 55°</u>
